14. Fendrick wants to buy a new dining room set for $900.
2
He is considering four methods of payment. After looking at his budget as well as his actual expenses for the past few months, he thinks he can save
3
$80 per month towards this purchase. He has four options, described in detail on the table below. Which option is best for him?
4
(1) He could use a layaway plan to avoid interest and pay exactly $80 per month, but he would prefer to avoid the $50 storage fee, and does not want to wait almost a year to have his dining room set.
5
(2) He could use the furniture store's installment plan that has a $100 downpayment and then charges $73 per month to pay off a 15% annual interest rate.
6
(3) He could use the furniture store's zero down plan that costs nothing for six months and then charges $180 per month to pay off an 18% annual interest rate..
7
(4) He could open a new credit card with a 22% annual rate and pay off exactly the $80 per month he budgeted.
